> {{TopDownRuleDriver.DeriveTrait.derive}} asserts that a derived node belongs to the same {{RelSet}} as the original node. 
> If the original node {{N1}} refers to set {{S1}}, the derived node {{N2}} might be registered in the set {{S2}}, if {{S1}} was merged to {{S2}} between the registration of {{N1}} and derivation of {{N2}}. 
> Currently, we compare the original set of the original node {{N1}} with the canonical set of the derived node {{N2}}. This leads to false assertions.
